Held on Kootenay Lake each fall, the Nelson Police Derbry attracts anglers from across western Canada and the north western United States with the help of the Royal Canadian Legion and several local community sponsors. 

Based at the Balfour Beach Inn, proceeds from the Derby go directly to the Kokanee Park Salmon School Program. This program offers elementary students from across the West Kootenays a unique look at spawning habits of our Kokanee Salmon and the impact this fish has on our fragile ecosystem. Program staff walk over two thousand students per year through this experience in nature.
